MEDIA ADVISORY REGARDING ERRONEOUS NEWSPAPER ARTICLE

BOSTON, MA, April 14, 2008 – Over the weekend the Sunday Express newspaper in the United Kingdom published an article that contained false and erroneous information. The article incorrectly claimed that two volunteers were hospitalized after participating in a clinical trial, involving a pharmaceutical product being developed for the treatment of addictions, at a PAREXEL U.K. site. This report is completely inaccurate. In fact, the study is running smoothly without incident.

Update: Sunday Expresspublished the following retraction on its website April 25, 2008 and in the hard copy edition April 27, 2008:

"On 13th April we published an article which incorrectly claimed that two volunteers were hospitalised after participation in an ongoing clinical trial run by PAREXEL International. In fact, we now accept that the incidents mentioned related to a significantly different version of the study drug and trials conducted in the USA in 2000 and 2002 by a company unconnected to PAREXEL. PAREXEL reports that their present study is running smoothly and without incident."
